SPRING-SEAT.

specification of Letters Patent.

Patented Oct. 10, 1916.

Application filed February 21, 1916. Serial No. 79,656.

Tol/lll wiz/0m t may concern Be it known that I, DENNIS B. SNYDER, a citizen of the United States, residing at Anderson, in the county of Madison and State of Indiana, have invented certain new and useful Improvements in Spring-Seats; and I hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement in spring seats and provides a new and useful spring construction for s eats particularly adapted for use in the seats of railway cars and the like where it is desired to provide a comfortable and durable spring seat, so constructed that the working partsv cannot readily get out of order, the length of life of the various parts is increased, and the liability of the spring plates to crystallize and break where their ends are attached to the frame is obviated.

The invention has particular reference to the means for retaining the spring plates in position in the seat and consists in the novel construction and arrangement of parts hereinafter described and claimed and illus# trated in the accompanying drawings,rin which Figure 1 is a sectional view through a spring car sea-t constructed in accordance with this invention. Fig. 2 is a fragmentary top plan view of the improved top spring structure. Fig. 3 is an enlarged detail sectional view on line 3-3 of Fig. 2. Fig. 4 is a detail sectional view on line 4-4 Fig. 2. Fig. 5 is a transverse sectional view of a seat showing a modified form of the top spring structure. Fig. 6 is a detail top plan view of one of the retaining strips shown in Fig. 5. Fig. 7 is an enlarged detail section on line 7-7 Fig. 6.

The seat may have any suitable base or foundation 1, upon which are mounted a plurality of coiled springs 2 of any suitable kind; the upper ends of which are connected to a plurality of spring plates 3, which extend over the top of the springs and substantially cover the same.

The expansion coil springs may have their lower ends secured to the foundation by any suitable fastening means and their upper ends may be secured to the plates 3 by rivets or other suitable means. The ends of said spring plates 3 are slidably engaged with chambers 4a formed in spring plate retainers 4, which are preferably formed of strips of sheet metalY bent longitudinally so as to be substantially U-shaped in cross section, see Fig. 4.

The retainers 4 are provided intermediate the chambers with indented portions 4b which are preferably flattened so that their inner opposed faces contact. The said portions 4b may be connected in any suitable way. As shown, one of the flattened portions 41 is formed with an opening 4c and the opposed flattened portion is slitted opposite such opening and the tongues 41 cut from such portion are bent to extend through the opening 4 and clenched as at 4e to hold the sides of the retainer firmly in place, see Fig. 3. It will be seen that there is a chamber 4a provided for each end of each spring plate 3, so that said spring plates can bow and flex when in use without straining their fastenings orv connections to the retainers; and the flattened portions 4b at the ends of said chambers prevent excessive lateral play of the spring plates.

Preferably the retainers 4 are strung upon the front and rear bars 6, 6a of a metal frame, which may be formed of a metal wire or rod bent into proper shape; the bars 6, 6a being connected by side bars or rods 6, 6d as shown in Fig. 2. Suitable pads 7 of rubber, or any other suitable material are preferably secured to the corners of the said metal frame to protect theseat cover and prevent wear. be urged upwardly by the springs Qagainst the under side of the cover 8 which may be of canvas, or other suitable material and tacked or otherwise secured to the foundation 1 and such cover will be stretched and the upper surface thereof present a smooth even surface.

The cover 8 may if desired be in turn covered by an outer covering 9 which may be secured in place by any suitable means, as is common in upholstering, thus completely incasing the entire spring structure, and the seat may be stuffed or cushioned between the covers 8 and 9 in the well known manner if desired. The spring plates 3 should have their top edges beveled or rounded so that they will not cut the covers.

In the modification shown in Figs. 5-7 the foundation 1 is provided with upstanding rigid pieces 1c at front and rear, to which the spring plate retainers are attached. In

The plates 3 will normally p this form the retainers 4 instead of having their bends engaged with wires or rods 6, 6 may be provided with apertures 1l through which pass fastening screws or nails 4h securing same to the pieces lc.

`From the foregoing it will be apparent that a particularly simple and efiicient spring structure is provided for use in connection with ear seat chairs or other upholstered articles wherein it is desired to provide a resilient support and it will also be noted that the possibility of the spring plates breaking at the points where they are attached to the frame is eliminated as their ends are free to move in the chambers 4a.

7h at I claim is:

l. In a spring seat, a base, chambered retainers adjacent opposite sides or ends of the base, and spring-plates extending across the seat and having their opposite ends engaged with the pockets in the retainers.

2. In a spring seat, a base, springs supported on said base, chambered retainers, and spring-plates supported on the springs and having their ends loosely confined in the chambers of said retainers.

3. In a Cushion seat, a base, chambered retainers adjacent opposite ends of the base, expansion springs mounted on the base, and spring-plates supported on said springs and having their ends engaged with the chambers in said retainers, substantially as described.

4. In a spring seat, a base, expansion springs supported on said base, U-shaped retainers adjacent opposite ends of the base, transversely extending spring-plates supported on the expansion springs and having Jtheir ends slidably engaged with the U- shaped retainers.

5. A spring plate retainer having a series of chambers adapted to receive the ends of spring plates, substantially as described.

6. A spring plate retainer formed of' a metal strip bent longitudinally upon itself and having spaced flattened portions at intervals forming chambers between adjacent flattened portions adapted to receive the ends of spring plates, substantially as described.

7. Spring-plate retainers formed of metal strips having spaced flattened portions forming chambers between adjacent flattened portions adapted to receive the ends of spring plates, and connections between the opposed flattened portions, substantially as described.

S. In combination a frame, chambered spring-plates secured to opposite ends of the frame, and bowed spring plates having their ends engaged with the chambers in said retainers, substantially as described.

9. A spring seat, comprising a foundation, expansion coil springs on said foundation, bowed spring-plates supported on the coil springs, U-shaped retainers at the ends of the spring plates, and rods extending through the retainers to hold them and the spring-plates in position.

10. In a spring seat, a base, a frame, U- shaped retainers secured to opposite sides of said frame, expansion springs secured to the base and extending upwardly therefrom, and spring-plates supported on the upper ends of the springs and having their opposite ends slidably enga-ged with the retainers, substantially as described.

l1. In a spring seat, a base, a metal frame, U-shaped retainers hung upon opposite sides of said frame, expansion springsl mounted on the base and extending upwardly therefrom, and spring-plates supported on the upperends of the springs and having their opposite ends slidably engaged with said retainers and a covering for the seat, substantially as described.

In testimony that I claim the foregoing as my own, I aiiiX my signature.
